' This invention relatest'o. dispensers for insectlelqellent materiah` and more particularly. to.. a dispenser attacl'iableA to the tail of,` an animal, such as acow or horse, to dispense insect-repellent material incident to the swishing ofthe. tail by the animal, in the.. attempt to remove, insects.

Itisamong theobjects ofthe inventionto provide: an improved insect-repellent dispenser of smalll size and'. light weight, which can, be easily seouredto thetaloiananimal, suchas, acow or.

Figure 9 is a somewhat diagrammatic view of a, cow showing the manner of attaching the insect-repellent dispenser to the tail of the cow.

With continued reference to the drawing, the dispenser comprises an elongated tube or capsule I0 of a pliable or resilient material, such as a synthetic rubber or synthetic resin material having ilattened, closed portions Il and i2 at its respectively-opposite ends. Between the closed 4 Claims.v (Cl. 11B- 157) portions. the tube or, capsule is filled with a,` body of insect-repellent material of any desiredcomposition and which may be in either powder` or,

liquid form, andthe wall of the tube between vtheA closed ends thereof is perforated witha large I3` which number of very small perforations will permit the repellent material to passslowly. through the perforated wall of thetube.

One of the iiattened end portionsis madesomewhat longer than the other, thisbeing the. por.- tion i2, as illustrated in Figure 1, and thispor.- tion isv provided with. two spacedeapart. clon-.- gated openings i4 and l5.

In attaching the dispenser, to ananimalpsome.v

oi' the hairs at thecenter of thegroupof hairs growingfrom thetail of, the animal are separated into-two strandsof suitable size, which strands. are passedrespectiyely through the openings` L4., and l 5, and tightly knotted adjacent` the portion oi thedispenser in which theseopenings are Di0- vided. A suitable cement, suchl as a quick-drying,

cellulosic cement, is then applied. to. the.. knot. iormedin the tailhairs of the animaLvso that,r these knots will notbeoome loosened or untiedi.

resulting in accidental ,lossof the dispenser.

The tube is of small, size, dimensionsof. ap.- proximately one-haliinch diameter and six inches in lengthhaving been found suoientto. containenough insect repellent tolast substantially through theseason of troublesome insect prevalence, is consequently light. in weight, and

becauseof 'this small size, light weight and. the;v

ilexible or resilient nature of the material of which it is formed, will not bruise or injure the animal when struck against the sides of the animal by swishing movements of the animals tail. The impact of the dispenser against the sides and back of the animal causes the repellent material to be dispensed through the perforations I3 and the rate at which the material is dispensed will thus be proportional to the rate at which the animal moves its tail to dislodge insects from its body, and this is more-or-less proportional to the prevalence of the insects. However, as the perforations I3 are extremely small, the material will be dispensed at a slow rate over a long period of time.

The form of the invention shown in Figures 4 and 5 is the same as that shown in Figures 1, 2 and 3, except that a small, screw-threaded iiller neck or eyelet I6 is secured in the hollow body or tube I0 adjacent one of the closed end portions of the tube, and a screw cap i8 is threaded onto the portion of this neck projecting outwardly of the body. By removing the cap I8. the body can be refilled with liquid repellent from a receptacle, such as a pressure-dispensing oil can, or a syringe.

The form of the device shown in Figures l, 2 and 3 is particularly adapted for use on range or grazing cattle, whereas, the form shown in Fgures 4 and 5 is more particularly designed for use on dairy cattle where insects, such as illes, are more prevalent, and the animals are more constantly cared for.

The form of the invention shown in Figures 6 and 7 is also generally similar to the form shown in Figures 1, 2 and 3, and described above. but in the case of the form shown in Figures 6 and 7, an elongated cake or cartridge I9 of repellent material is placed in the tube before at least one of the end portions of the tube is flattened and sealed to close the tube. This cartridge I9 may be of elongated, generally cylindrical shape and preferably has annular ribs or extensions 20 spaced apart longitudinally thereof to maintain the major portion of the surface of the cartridge or filler out of contact with the wall of the tube. Also, the perforations 2| in this modied form of the invention, are made larger than the perforations I3 in the forms illustrated in Figures 1 to inclusive, since it is mainly the vapor or sublimation from the solid core I9 which passes through the perforations. rather than the material of the core itself.

Because of the modified size of the perforations the tubular body of the form of the dispenser illustrated in Figures 6 and 7 is designated as I0'. the closed end portions as Il' and I2' and the openings for attaching the dispenser to the tail of an animal as I4 and l5.

Because of its small size. light weight and pliable or exible nature, the device causes no discomfort, inconvenience, or injury to the animal to which it is attached, and is highly eiective in repelling insects from the animal.

` The inventionV may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are, therefore, intended to be embraced therein.

What is claimed is:

1. An insect-repellent dispenser comprising an elongated, perforated tube having closed ends 4 and a body of insect-repellent material therein, said tube having apertures in the Wall thereof for dispensing insect repellent material when the dispenser is struck and having at one end a attened portion provided with spaced apart slots for receiving strands of hair of an animals 'tail and through which such strands may be tied to secure the dispenser to an animal. x ,v Y

2. An insect-repellent dispenser comprising an elongated tube of flexible material having flattened, closed portions at its opposite ends and perforations in its wall between such closed end portions, one of said closed end portions having spaced apart openings therein for receiving strands of animal hair to attach the dispenser to the tail of an animal.

3. An insect-repellent dispenser comprising an elongated tube of iiexible material having flattened, closed portions at its opposite ends and perforations in its wall between such closed end portions, one of said closed end portions `having an opening therein for attaching thedispenser tojthe tail of an animal, a. screw-threaded ller neck projecting from said tube near oneof said closed end portions. and a closure capv threadedv onto' end portions. said cartridge having spaced-apart,l

annular ribs thereon to maintain the wall of said tube out of conact with the cartridge.
